INCINERATOR.

Application led November 21, 1924. Serial No. 751,263.

This invention relates to an-incinerator, and has special reference to that class of garbage and refuse burners or furnaces adapted to be built into a building, whereby the garbage and refuse from different parts of the building may be disposedA of by burning. In the operation of such incinerators,

' the draft is often stopped by the clogging of the feed chute by the refuse, which chute is also the draft flue, and such stoppage results in'escape of smoke and fumes into the building, causes a smoldering fire and often produces complete 'cessation inv the operation of' the incinerator.

These incinerators as commonly installed in apartment and other buildings have a stack or similar structure rovided with a draft flue and into which ue the refuse is dumped at the several floors of the building, and this refuse accumulating in the furnace and often lodging in the flue, shuts off the draft through the flue; and it is an object of the present invention to provide -a construction wherein there will always be an open passage for lthe smoke, gases and fumes,

. leading from the combustion chamber of the furnace to the stack above such stoppage or accumulation, whereby stoppage of the draft is prevented, combustion is insured, and the escape of smoke and gases into the building is prevented. A further object is to permit of the filling of the combustion chamber with refuse, thus requiring less frequent burning, and also permitting of the lighting and burning of the accumulation at the bottom of the pile Where it is the driest and most combustible, so that the burning of the driest portion will dry out the moist portions above and the entire mass will'be completely vand rapidly consumed.

- A further object is to provide an incinerator which may be separately constructed and installed in the usual manner and is adaptable for installation in various building structures. Y

lVith the above and other ends in view,

the invention consists in providing an auxiliary flue which is separate and distinct from the main flue which also forms the refuse chute, and connectiuo' this separate flue with the main flue to. disc large smoke and fumesv into the main flue at a point or points above those places in the main flue where stoppage may occur. It also consists` in providing a passage or passages leading from the lower part of the combustion chamber ofthe furnace ind connected with said auxiliary flue, whereby the refuse may be burned from the bottom of the pile and maintenance of combustion is assured regardless of the amount of refuse' in the re chamber and main Hue. The invention further consists in certain other new and useful features in the construction and arrangement, all as hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing` in which- Figure l is a vertical longitudinal sectional view of the furnace portion and a short section of the stack of an incinerator illustrative of the present invention Figure 2 is a transverse vertical section of the same;

Figure 3 is. a horizontal section substantialy upon the line IIL-III of Figure 1, an

Figure 4 is a side elevation of an incinerator with its stack broken a-way and in section, the same being drawn to a reduced scale and illustrating it as installed in a building. i

In the drawing, the reference numeral 1 indicates a rectangular furnace construction` of masonry which may be of any suitable form or size according to the requirementsv 0f installation, and to provide` acombustion chamber 7 which may be provided with la refractory lining 2' and has the usual doorway 3 in the fi'ont wall thereof provided with a fire-door 6. l The furnace is also provided with the usual ashpit 5 having an ash door 4 and a grate 8 above the ashpit forms a portion of the bottom of the combustionI chamber, when the doorway 9 may, if found desirable, be provided in the front wall of the furnace through which doorway access may be had to the upper portion of the combustion chamber for ythe purpose of poking the burning material or for other purposes, and this 'doorway is closed by a door 10.

Extending upwardly from the top of the structure, a chimney or stack 11 provides a main draft flue l2 which opens at its lower end directly into the top of the combustion chamber 7 and extends throughout the height of the stack which will preferably extend through or beyond the roof of the building and past the several floors 18 thereof. This main iue 12 not jonly provides a chamber, a short lateral chute 19 being provided at each floor through which the garbage and other refuse ma Y be deposited in the main chute, said lateral c utes each being provided with a suitable tight closure 20, as is common in this character of structures..

To provide a passage or passages for the products of combustion and create a draft to carry olf the odors and gases, when the lire chamber of the furnace has become filled with refuse as indicated in Figure 1 and so that the accumulation may be set on fire at the bottom, a vertical wall of the chamber,

preferably the front wall thereof, 'is formed with a plurality of inwardly projecting ribs forming between them a series of vertical passages 17 extending from near the top of the grate 8 to the upper end of the chamber,

each passage being open throughout its length at its inner side or toward the refuse contained in the chamber. This refuse falling into the chamber through the chute 12 will pile up against the inner edges of the ribs but wi l not enter the assa es 17 between the ribs sufficiently to c ose o these passages. There is therefore always provided these open passages leading from near the rate below the vaccumulation of refuse, to t e top wall of the furnace, so that the refuse at the bottom of the pile `which has become thoroughly dried out, may be set on re and the prodf ucts of combustion will find a passage past the'accumulated pile through these several passa es 17. As the pile of refuse in the chamer may thus be burned from the bottom, and as the bottom of the pile is always the driest, the heat of burning and the upwardly ascending products of combustion will quickly dry out the wet garbage and refuse at the top'of the heap so that the entire pile will be quickly consumed. This are rangement of assages therefore permits of lling the entlre combustion chamber with refuse before burning, and the operations of burning may therefore be less fre uent, giving a greater length of time for t e drying out of the refuse at the bottom of the pile.

As illustrated in Figure 1, the refuse may accumulate until it not only fills the combustion chamber, but also the lower end portion of thelmain flue or chute 12. If this should occur, the draft through this main flue would be shut otf and the products of combustion could not escape up t e chimney. They would however escape into the building as would also the fumes from 'the accumulated refuse before it is set onl fire. To provideA for such a contingencyr and also to provide for the contingency of refuse being floor;

-ney and lodged in the main flue or chute at points between adjacent floors, the chimney or stack is provided with an auxiliary flue 13 extending along one side of and parallel with the main fiue 12. This auxiliary flue opens at its lower end directly into the top of the combustion chamber of the furnace and extends upwardly rin the stack` any desired chstance, but preferably to a point beyond the upper floor of the buildin or adjacent te the lateral chute 19 locate at this upper vals throughout the length of this auxiliar) flue 13, which openings afford communica tion between the auxihary flue and the main iiue 12. These openings 21 are located abov(` and below the horizontal planes ot the lateral chutes 19 and therefore should refuse become lodged in the main flue below any any one of the lateral chutes and stop the draft through the main flue, the smoke, fumes or gases passing up the main tiue may pass throughone of the openings below the stoppage in the main liue, into the auxiliary fiue and then back into the main iue again through an upper opening above the stoppage. The auxiliary flue therefore provides a bypass around any stoppage which may occur ih the main Hue and the smoke or gases will therefore always be carried up the chimprevented from escape into the building.

To provide for and insure communication between the u per ends of the passages 17 and the auxiliary liuc 13, an extension is provided for the wall of the main flue 12 adjacent these passages, to extend downwardly a short distance within the combus-V tion chamber, and a like downward extension is provided for the wall dividing the main flue from the auxiliary flue. This wall extension in its preferred formas shown, is a channel beam 22 which extends across the upper end of the combustion chamber with its ends imbedded within the side walls of the chamber, and provides a supportfor the front side of the wall of the flue 12. A similar channel beam 23'is secured at one end to the beam 22, with its opposite end. imbedbed in the back wall of the4 chamber and forms a support for the dividingwallv hetween the fiues 12 and 13. 'The beam 22 which in elect is a downward extension of the front wall of" the flue 12, prevents the l"refuse )assing down the flue from accumulating wit in the frontup er corner of the com- Openings 21 are provided at interbustion chamber, and t us provides an open space within the corner at all times, no matter how full of refuse the chamber may be,

and thus keeps the upper ends of the passages 17 open at all times and provides an open space between the upper ends ot' these pasages and the extension 22 of the wall.

An opening or openings 24 are provided in the beam 22 to afford communication between and provides a downward extension for the di# viding wall between the flues 12 and 13, separating thespace at the lower end of the flue 12 within the chamber from the space within the chamber at the lower endof the flue 13.

Should refuse accumulate within the combastion chamber and till the lower end ortion of the main flue 12 as illustrated in igure l, thus effectually closing thelowcr end l of said flue, then the smoke and gases passing upwardlythrough the passages 17 may pass across the open corner space within the chamber through the opening and directly into the lower end of the auxiliary flue 13. An open passage is therefore always .provided from the lower part of the combustion chamber near the grate upwardly to and out through the auxiliary line.

Vith the present arrangement of passages 17 which are open at one side' throughout their length to the combustion chamber, the

- products of combustion may always enter directly into these passages Aand are. never forced to descend within the combustion chamberinlorder to find an outlet to the stack. The arrangement of these passages together with the auxiliary flue insures an open passage for the products of combustion and gases at all times up the stack and out through its open up er end, and a'draft is always created whlc e'ectually draws off all odors, gases and smoke. The auxiliary passage within the stack by being provided with the several openings 21 into the main ilue 12 provides at all times a b -pass around any obstruction which may c ose the main flue and thus all yodors and gases which would otherwise be trapped within the main iiue will be drawn oft' by the draft created through this by-pass.

Obviously any suitable means other thanl the channel beams 223and 23 may be provided for the purpose of affording at all times an open passage from the upper ends of the' passages 17 vto the lower end of the l auxiliary'v flue, and to also rovidesuch a passage to the lower end o the main iue when this flue is not obstructed. These channel beams however provide such ,a pass e and at the same time afford a verf,1 rigld support for the lower end of the stack upon the upper end of the furnace. The passages 17 may also be formed other than by providing ribs upon the wall of the chamber,

and it is also obvious that other changes in the specific construction and arrangement of parts as shown may be made within the scope of the appended claims without deylower end with the upper end of said passage and opening into said main flue intermediate the ends of the main flue.
